Melting and crystallization behavior of a high-T c compound Ba2YCu3O x was investigated by microstructural observation, and compositional, thermal and X-ray analyses. Because of an incongruent melting, Ba2YCu3O x decomposes into a solid phase, Ba2YCuO5, and a liquid at 1266 K in air. Ba2YCu3O x crystals are formed around the primary crystals, BaY2CuO5, by a peritectic reaction on cooling from 1473 K in air.
